Christoph Hellwig 704f2c20ea dma-direct: reject highmem pages from dma_alloc_from_contiguous ... dma_alloc_from_contiguous can return highmem pages depending on the setup, which a plain non-remapping DMA allocator can't handle. Detect this case and fail the allocation. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Robin Murphy <robin.murphy@arm.com>		2018-12-01 17:56:08 +01:00
